Bug Description
Hello,
This bug affects oneiric and precise. Previous versions of Ubuntu used to carry a patch 215_glx_
The patch was removed in oneiric (xorg-server-
However, as noted in the original bug report, that commit doesn't fix the problem when using radeon UMS. You need to add the patch in comment 40 of that bug report, or alternatively, remove the upstream commit and re-apply the 215 patch.
Without the patch(s) I get very frequent crashes of the Xorg server when using an OpenGL window manager. Just un-minimising a window in kwin will usually cause a crash. I'll include an Xorg log of a crash for you. It is basically unusable and I have to revert to non-opengl.
Radeon UMS was removed in quantal so I can't test any newer versions of the package. KMS doesn't have this particular problem, but has its own problems and UMS is still the best option in 12.04 for radeon PowerPC. I probably should add that to get UMS open-gl in precise I have to install an older 7.11 version of libgl1-mesa-dri.
Thanks
Release: 12.04
